Filter articles by subject editor (OJS

We are publishing a journal with 5 different subject areas, each one of them having 3 subject editors. It is now possible to filter by subject area, but not to filter so as to know how many articles is each subject editor handling (which was possible under OJS 2 I think).
This is important because we try to distribute the load of work evenly and the only way to know how many articles has each subject editor is to log in as them and see in their dashboard how many articles are they processing. This is quite unpractical.
Is there any chance of including this new filter anytime soon?
Best regards!
